The Challenge

The site has a closed loop lake that captures all water and the lake was used for fire-fighting training water.

With the nature of the site, the hydrocarbon is used as an accelerant for fire training. The Hydrocarbon was running off site, due to no containment system, and into the lake resulting in a large sheening.

As the site was, there was nothing to contain any hydrocarbon spills if there was a catastrophic failure.

This meant that the facility had to close down the reuse of the lake water and use mains water as an alternative. The catchment is a mixture of unsealed and sealed catchment with high TSS and Hydrocarbon loadings. Due to nutrient buildup from the runoff, algal blooms were experienced.

Our Solution

The AKS Team (SPEL Victoria & Tasmania) worked with the project team to design and construct a turnkey package.

Due to a limited budget, a staged approach was taken.

By pre-treating all low-flow runoff through the SPEL Puraceptor, then running the water down a rock beached swale prior to entering the lake, the runoff is cleansed from any hydrocarbon spillage in normal rainfall conditions.

Once the water is in the lake, through the use of an aerator, the flow is directed through the floating wetlands.

The Floating Treatment Wetlands are unique in the way that they are not affected by rising and falling water levels; this meant that during summer, the client could draw down the water level more without fear of the system suffering.

The result is that the severe algal blooms are now history and the frogs have returned to the water body for the first time in years.

Why SPEL?

Complimentary Modelling Service

SPEL is the water specialist with over 40 years of experience and we can help in your project.

To predict the performance of stormwater quality management systems and aid in decision making, we employ Model for Urban Stormwater Improvement Conceptualisation (MUSIC). It is intended to help organisations plan and design (at a conceptual level) appropriate urban stormwater management systems for their catchments.

This is a complimentary service from us at SPEL which will help you identify the right solutions for your projects.

Design Assistance

The SPEL Environmental design team is committed to continual improvements of both structure and water quality across the diverse range of products used in the storm water and wastewater industries.

We are continuing the standard of excellence with the latest and most up-to-date equipment to ensure the
development of high quality, efficient, environmentally sensitive products. The use of AutoCAD, Solid Works, 3D
Modelling, FEA Analysis are only a part of the detail used to enhance our products.

Simple Installation

We understand easy installation is a key consideration in your project. Thus all our products are designed with this in mind.

Our tanks are made from fibreglass reinforced plastics (FRP) which has a high strength-to-weight ratio and are easy to be transport & install. The floating wetlands can also be easily deployed to lakes and stream within a day.

We will provide any technical support, at your request, and installation manuals for your reference.

Easy Operation & Maintenance

SPEL products are easy to operate, maintain and are long-lasting.

Our tanks come with a 25 years warranty and all products' maintenance are hassle-free.
